RP200 equipment with DVI-VGA sending auxiliary stream, the auxiliary flow trimming serious problems arise

Publication Date:  2013-09-30 Views:  171 Downloads:  0
Issue Description
In the newly installed RP200 game point for auxiliary flow sharing, using DVI-VGA Cable sharing secondary flow in the auxiliary flow image you see on screen is not full screen, the image appears to be a serious trimming auxiliary flow problems. When using HDMI-DVI cable to connect the computer and the interface box when no auxiliary stream image output.
Alarm Information
Secondary flow was trimming tensile deformation, no output auxiliary flow.
Handling Process
1 When using DVI-VGA Cable sharing secondary flow, secondary flow trimming serious, change the terminal stretching mode output configuration parameters, set it to not stretch, the problem remains.
(2) In the first case, change the resolution parameter notebook from the smallest to the largest change 800 * 600 1366 * 768, the question remains the same, there are still trimming auxiliary flow problem.
3 due to the RP200 device is equipped with a TV, TCL TV, so the TV parameters can be modified, picture-> picture size-> native, in accordance with the above parameters can be modified, the auxiliary flow picture is normal, the problem is solved.
4 When using HDMI-DVI cable to connect the computer and the interface box for auxiliary flow sharing, no auxiliary stream image output, connect the cable directly to the terminal HD IN2 port, auxiliary streams can be found in the normal output, but through the interface box adapter connect to HD IN2 port, the auxiliary streams can not be output through the development of post-confirmation, RP200 is equipped with interface box 201 currently only supports transmission of analog signals, digital signals for transmission of HDMI that are not supported, so by sharing auxiliary interface box stream, currently only supports DVI-VGA cable sharing secondary stream.
Root Cause
1 terminal output setting mode selection tensile stretching or smart stretch.
2 notebook resolution parameter mismatch.
3 TV parameters do not match.
4 HDMI terminal does not support the format auxiliary stream input.
5 interface box does not support HDMI format auxiliary stream input.
Encounter problems related to such secondary flow, you can stream from the secondary sender -> Secondary flow recipient, has been playing to a secondary stream side, every step carefully examined to check each step of the relevant parameters configuration, and the corresponding device matching relationship to try several times, so as to ultimately determine the fault of the problem, solve the problem.
